T0 all whom 'it mayconcewi A Be it known that I, Louis JAY PERKINS, a citizen of the United States, and a resident ofLewiston, in the county of Nez Perce and State of daho, have invented certain new and 'useful Improvements in TireMount-' ings, of which the following is a specification. l v

My invention is an improvement in tire mountings, and has or'its object to provide a mounting of the character specified vadapted for use in motor vehicles of any character,.wherein the edges of the shoe or casing are` so arranged that they may be pressed tightly together to seal the casing, and wherein means is provided in connection with the rim for securely clamping the said f edges together.

In the drawings:

Figure 1 is a radial ysection of a wheel hav ing the improved tire mounting;

F ig. 2 is an edge view showing the manner of placing the tire;Y A Y.

Figs. 3 and 4 are 'views similar to Fig. 1, showing modiiied constructions.

In all of the embodiments shown the shoe or casing 1 may be of any usual or desiredv formation, but theiedges thereof are adapted to abut and to be' clamped together to seal the shoe or casing. The edges 2 and 3 'of the tire have their abutting faces meeting at an incline as shown, and,y the edge 2 has a. iiap i which is adapted to underlie the edge 3.

, This flap i is triangular in cross section as shown, the oppositev faces meeting at an acute angle, and thenpper face is inclined,

inclining downwardly :tromthe abutting surface above mentioned tothe free edge of the flap. That face of the edge 3 which .abuts the upper face of the iiap is inclined to fit, and it will be noticed that the abutting facey of the wall 2- is undercut, the arrange ment being Such that the more firmly the edges are pressed toward each other' the more closely they will engage at the abutting faces. v

Because of this construction any torce which tends to press the edges together sists in sealing the tire, 'and the improved tire may be used with demountable rims or with wheels not provided witi such rims. In F ig. 1 the tire is shown in connection with a demountable rim. 'ln vthis construe tionthe rim 'lias at one sideedge a for engaging the shoe att ieedge Zand the other edgeof'the tire'is engaged by 4a retaining ring which is held on the demountable rim by clamps to he described.

Referring to F ig. -l, it will be seen that the peripheral surface of the demountable por-` tion 5.0i the rim isconical throughout some thing like two-thirds of its width, as indicated at 8, the remaining surface 9 being cylindrical. The smallest diameter of the tapering; portion is internal or inward, merging with the cylindrical surface 9. AThe inner surface of the shoe as a whole is shaped to fit this tapering surface 8 lof the-demount-- able portion of the rim, and a portion of the cylindrical surface 9, and a retaining ring 7 tits on this cylindrical ring does not become'tighter as it is moved.

inward toward the'flang'e 6. Thus by meansl of the ring 7 the edges 2 and 3 of the shoe may be tightlyclamped together.

The rim 10 of the wheel vwhich is fixed is seated on the telly 11,"and 10, which is cylindrical, has at one side edge an outwardly extending flange 12. The -demountable rim 5 has on its inner surface and at the junction of the tapering and cylindrical portions an annular rib 13 which is'ada'p'tedto engage the outer surface o f thev rim 10, and the flanged or large side ofthe demountable rim engages the flange 12. This rim and the rib 13 are so proportioned that the. shoe or casing will. bel I proper position `with re-v supportedv in the spect to the wheel.

rlfhe clamping mechanism for forcing theor lug will drive the' retaining ring in; ward, to tightly ciampl the edges 2 and 3 of the shoe together. Each of the clamps 14 has a laterally extending lug 20 on its inner surface, vso that the eo f face, adjacent to the lug 16, which fits between the deiiountable portion of the rim 5 and the xed portion, and each of these lugs 2G is berelcdat" its end, as shown, to facilitate its entrance between the two portions of the rim. The shoe yor casing has the usual i al,

an valve 2l for permitting i- 3o be, inflho said valve extending nsoiigh Elio inn and lolly, as shown.
